Answer:
[tex]f(g(x)) = \sqrt{8x - 4} [/tex]
Step-by-step explanation:
[tex]f(x) = \sqrt{x + 7} \\ \\ g(x) = 8x - 11[/tex]
To find f(g(x)) substitute g(x) into f(x) that's for every x in f (x) replace it by g (x)
We have
[tex]f(g(x)) = \sqrt{8x - 11 + 7} [/tex]
We have the final answer as
[tex]f(g(x)) = \sqrt{8x - 4} [/tex]
Hope this helps you
